Thanks for the intel. I wasn’t aware of this. The Sierra rep stated the 158 JSP is designed around 357 from a rifle, so I imagine it’s the best suited to hold up in this scenario. The 250 sub-x I can’t say. I was told it’s been tested to 1600 fps, but no idea if it’ll hold up to the forcing cone
.350 Legend from a handgun.

I have been shooting .500 S&W, 45/70 and 30/30 from pistols. They are a lot of fun for big game. The below web site has 350L loads.
Shooter's Reference Load Data for .350 Legend
Thanks for the link. Presumably, all that data is from rifle length barrels. I'm hoping to find some intel on where to start from pistol length barrels. I may be making too much out of it though. I picked up some 4227 today and will start there as I have managed to dig up published data for both the 158 and 250. Just need to find a chrono to borrow as my magnetospeed isn't meant for handguns.I have been shooting .500 S&W, 45/70 and 30/30 from pistols. They are a lot of fun for big game.

Yes, the info is just for rifles that said when shooting from a pistol FPS will be less. I found when shooting a 45/70 or a 30/30 from a BFR 7.5" revolver you could see a decrease in FPS from 100FPS to 300FPS depending on load and powder. When I shot a .500 S&W mag pistol load from my carbine, I found the FPS could increase from 100FPS to 350FPS.
Keep in mind, 357 pressure max is 35,000 psi and 350 Legend is over 62,000 psi. Quite a difference for a bullet designed for 357
That's an interesting point. The Sierra rep discussed the velocity window we figured we'd be hitting the target with, but pressure was never considered in the discussion. What would be the repercussions here? Bullet coming apart after leaving the barrel? Being compromised while in the barrel and coming apart out side?

As I said before, my concern would be deforming the jacket as it enters the forcing cone and raising pressures. If Sierra is ok with it then go for it
A quick update for anyone still following along. After some experimentation I managed to get my magnetospeed sporter rigged up to reliably read on the revolver. I've only used IMR4227 so far, with both the 158GN Sierra's and the 250 gn Hornady Sub-x. I haven't maxed out pressure signs, but have shot the 158's up to 1740 fps. When comparing my velocities to the published velocities, I'm coming in 500 fps short for a given powder charge. With the 250's I have only seen 1140 fps, although I have not loaded as far up the scale and expect to see higher speeds before seeing any pressure signs. For a given load, the speeds are coming back at 400 fps below book numbers. Neither Hornady nor Sierra state what length barrel they used.
All in all I'm a bit dissapointed with the speeds. I was hoping to stay closer to 300 fps below book. Other powders may provide better results. That being said, the 158's at 1740 gives a muzzle energy of 1060. This is legal for deer in my state, and ought to provide acceptable results.
The 250's would need to get to approx 1380 fps to match the energy of the 158s at 1740. Given my findings being 400 fps below book speeds, I don't see anyway to achieve that 1380. Again, maybe a different powder will give speeds closer to book. I'll continue to dabble with the 250's as time allows, but atleast for this hunting season, I'll focus on the 158s.

Try the Hornady 165 ftx bullets. I’m getting them around 1700fps. Mainly I just shoot the Hornady black 150grn ammo. I’m getting around 1880fps. That is very impressive from a 6.5 inch barrel. Hitting with around 1200lbs of energy. Hits harder than a 44 mag with less recoil. Not counting the buffalo bore stuff
Sorry, just wanted to clarify, are you getting 165/1700fps and 150/1880 from a handgun?
